Zero-Knowledge Biometrics

Passwords are failing. One-time passcodes are expensive. Device-native biometrics don’t go far enough. And centralized biometric databases introduce privacy and compliance risks that today’s organizations can’t afford.

At the same time, AI-driven impersonation, deepfakes, and account takeover attacks are escalating — forcing security leaders to rethink how identity assurance is delivered across digital journeys.

This solution brief from Ping Identity introduces a new model: zero-knowledge biometrics — a privacy-preserving, cryptographically protected approach that delivers true multi-factor authentication in a single, seamless step.

Based on the Ping Identity Platform, this brief outlines how organizations can strengthen authentication, reduce operational costs, and protect biometric privacy — without adding friction or architectural complexity.

What you’ll learn in this brief

• A new standard for biometric authentication – Why traditional passwords, OTPs, and device-only biometrics fail to meet modern identity assurance and privacy demands — and how zero-knowledge biometrics closes the gap.
• True multi-factor authentication by design – How inherence (face) and possession (device) are verified together in a single glance — authenticating the person, not just the device.
• Privacy-preserving cryptography in action – How one-way cryptographic transformations ensure biometric data is never stored in a retrievable or reconstructable form — whether processed on device or in the cloud.
• Deepfake-resistant security – How AI-driven liveness detection and injection protection defend against modern threats including spoofing, synthetic media, and impersonation attacks.
• Frictionless user experience at scale – How authentication can occur in under 300 milliseconds, with silent enrollment and seamless device binding — reducing reliance on passwords and SMS OTP.
• Business impact beyond security – How a Tier-1 European bank reduced account takeover fraud by 79% in the first year and achieved multimillion-dollar savings by lowering OTP and helpdesk costs.
